I'll readily concede that de-duplication isn't going to get you much, once you start talking about uniquely-encrypted data. 1MB just sounded much larger than what I've read and seen. At that size, yeah, about the only thing you're going to be de-duplicating is entire files. Interesting that smaller block sizes don't de-duplicate enough in practice to justify it.
